1. Function
The radio-control presence detector (fig. 1.a) permits
to achieve optimal energy savings by controlling the
illumination of a room depending on the presence of
persons.
1.a)
The detector is equipped with a passive infrared sen-
sor (PIR) and responds to thermal movements trig-
gered by persons, animals or objects. The detector
transmits a radio data telegram which can be pro-
cessed by all radio-controlled dimming and switching
actuators from release R2 onwards (see. identifica-
tion on actuator).
The presence detector activates a programmed ra-
dio-control actuator whenever the ambient brightness
drops below an adjustable reference brightness and
whenever movements are detected. The actuator
then controls the light intensity depending on the re-
ference brightness.
The light control remains activated as long as the pre-
sence detector detects movements.
If no movements are detected anymore, the detector
switches off after the preset shut-off delay. The detec-
tor is equally switched off when the upper brightness
limit is exceeded. .
For monitoring of large areas, several presence de-
tectors can be used in common in the same system.
In this case, one presence detector works as the mas-
ter unit (main unit) whereas all other presence detec-
tors work as slave units (extension units).

Important:
If the user wants the light control to be active imme-
diately after a person enters the monitored surface,
it is recommended to switch on the light control by
hand (cf. chapter 6.2 and 7.2) as it will otherwise take
a few seconds until the light control is activated by
the presence detector.
The reason for this is that - to avoid false triggering -
the detector’s sensitivity is initially reduced as com-
pared to that of a movement detector.
